Setting up the SPITFIRE 3 and first-flying
sink increases greatly when the
trimmers are opened!
Trimmer positions
•
Best glide: Trimmers fully closed
and easily on the C-Bridge (let arms
hang down).
•
Highest collapse stability in
turbulent air: trimmers completely
closed and "actively flying" with the
brake handles
•
Maximum speed in steepest flight:
trimmers completely open, 0%
brake
•
Minimum sink: approx. 50% brake
•
Minimum sink in turns: trimmer
fully closed
•
Maximum height loss in curves:
trimmer fully open
Facts about the trimmer settings
•
The trimmers not only change the
sink rate, but also the response of
your SPITFIRE 3 to weight shift. Your
SPITFIRE 3 responds best to weight
shift with the trimmers closed. It
reacts least with the trimmers fully
open.
•
The more you open the trimmers,
the longer the braking distances
will be. The position of the brake
handles in the zero position is then
further up.
•
The trimmers affect the length of
the braking distances, but not their
minimum airspeed. This means that
your touchdown speed does not
depend on the trim position.
•
Your SPITFIRE 3 will become more
"pitchy" the more you open the
trimmers, which means, for
example, that it can shoot forward
more during take-off.
•
Avoid flying for long periods with
the trimmers fully open and the
brakes applied sharply. You may feel
a slight vibration on the brake.
WARNING
Never fly with the trimmers
completely open in turbulence!
Basic rule:
Closed trimmers:
